Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FP1E331AV is determined by strict equivalence across the following critical parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - SMD (exact match required)
Physical Dimensions: 0.315" Dia (8.00 mm), Height 0.425" (10.80 mm), Land Size 0.327" L x 0.327" W (exact match required)
Mounting Type: Surface Mount (exact match required)
Polarization: Polar (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)
Compliance: AEC-Q200, ROHS3, MSL 1 (exact match required)

The Panasonic EEE-FK1E331AV meets all substitution criteria. While the EEE-FK series exhibits higher ESR (160 mOhm @ 100 kHz versus 80 mOhm) and lower ripple current ratings, these differences remain within acceptable operational parameters for the specified capacitance, voltage, and package class. Both parts share identical mechanical footprints, thermal ratings, and automotive compliance certifications.

Engineering Selection Recommendations

Both the EEE-FP1E331AV and EEE-FK1E331AV are active production parts with identical AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 ratings. Selection between these parts should be based on application-specific ripple current and ESR requirements.

The EEE-FP1E331AV (80 mOhm ESR, 850 mA ripple current @ 100 kHz) is suitable for applications requiring lower equivalent series resistance and higher ripple current handling capacity.

The EEE-FK1E331AV (160 mOhm ESR, 600 mA ripple current @ 100 kHz) remains functionally equivalent for applications where the specified ripple current and ESR characteristics are within acceptable design margins. Both parts maintain identical mechanical compatibility, thermal performance, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1E331AV be used as a direct replacement for the EEE-FP1E331AV?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), physical dimensions (0.315" Dia, 10.80 mm height), land size (8.30 mm x 8.30 mm), and compliance certifications (AEC-Q200, ROHS3, MSL 1). The primary difference is ESR and ripple current rating. Substitution is valid when application ripple current requirements do not exceed 600 mA @ 100 kHz.

Q: What is the difference in ESR between these parts?

A: The EEE-FP1E331AV has 80 mOhm ESR @ 100 kHz, while the EEE-FK1E331AV has 160 mOhm ESR @ 100 kHz. This difference affects heat dissipation and voltage ripple performance. Applications sensitive to ESR should specify the EEE-FP1E331AV.

Q: Are the physical footprints identical?

A: Yes. Both parts have identical dimensions (0.315" Dia, 0.425" height) and surface mount land size (0.327" L x 0.327" W / 8.30 mm x 8.30 mm). No PCB layout modifications are required for substitution.

Q: Do both parts meet automotive standards?

A: Yes. Both the EEE-FP1E331AV and EEE-FK1E331AV carry AEC-Q200 automotive qualification and are rated for -55°C to 105°C operation with 2000-hour lifetime at 105°C.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
